Abstract

Summary

We have compared field test data from a next generation node based CSEM acquisition system with data from a reference conventional system in a shallow water environment. The next generation system with much higher transmitter dipole moment and more sensitive receivers provides a step change improvement in the data quality, with clean data for all source frequencies out to 20 km offset compared to around 10 km offset for the reference system. The high data quality also provides clear improvements in the inversion results. This was demonstrated by improved imaging of a hydrocarbon accumulation under challenging conditions. We expect a maximal imaging depth, relative to the seabed, of up to 4500 m in future surveys with a commercial version of the next generation acquisition system.
